I've seen this issue already in this forum and I've tried all the suggested solutions. Even ran the FSX scanner. So, let me tell you something about my configuration and maybe that will trigger some specific answer for my setup. In addition to my FSDT KORD scenery, I also have FlyTampa's KMDW, as well as MyTraffic 6 installed and active. Could there be some conflict in this configuration? I am running FSX on Windows 7 Professional.
Thanks for any help.
